Keeping your heating system well-maintained is essential to extending its lifespan while also improving energy efficiency for your home. However, a heater can begin to make strange sounds over time. Always inspecting the source of these sounds is important to avoid potential damages. Contacting a heating repair company is always a smart idea if you are unable to figure out why your heating is making these weird noises.

Here are a few of the most common reasons why a heater makes strange sounds.

Ignition Problems

You may be dealing with ignition problems if you hear a loud banging noise once the furnace turns on. A small amount of gas can build up in the chamber, which creates the banging noise during the ignition process. Problems with your ignition can also happen due to other reasons, so scheduling an appointment with a technician is important to determine the cause of the noise.

Limited Airflow

A whistling sound often occurs in a furnace due to a blockage in airflow. Replacing the air filter can usually fix this problem, so it’s a good idea to switch out your air filter every few months. Closed vents or objects in the ductwork can also create whistling sounds while the furnace is on. Opening up the vents can resolve this problem, or you may need to reach out to an HVAC company if the problem persists.

Fan Problems

A clunking or knocking noise in your furnace can happen if the blower fan becomes misaligned over time. The blades may be hitting the walls or other areas of your furnace. A cracked fan belt can also cause these sounds, as the safest option is to contact an HVAC technician to take a look at your furnace to find the source of the problem.
